Abstract

A gateway apparatus includes a first network controller, a second network controller, and a time synchronization control unit. The first network controller has a first timer time-synchronized with nodes within a first network domain. The second network controller has a second timer time-synchronized with nodes within a second network domain. The time synchronization control unit includes a processor configured to store the observed times of the switching points of synchronized time slots within the first network domain, based on system time within the second network domain, and adjusts the rate of the second timer based on a comparison of a time difference between the successive observed times and a nominal length of the time slots.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application claims the benefit under 35 USC 119(a) of Korean Patent Application No. 10-2014-0123734 filed on Sep. 17, 2014 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.BACKGROUND[0002]1. Field[0003]The present application relates to technology used in connection with a gateway for heterogeneous networking within a vehicle.[0004]2. Description of Related Art[0005]Automobiles have been equipped with an increasing number of electronic products. The electronic products have been provided with a wide variety of additional sensors and control devices. Some of the products connect to an external network. Accordingly, various types of network technology that can be used in automobiles has also been developed.[0006]For example, parts historically operated using hydraulic components or mechanical components have been replaced with sensors. For example, to reco...
